Question

Two students are perfectly balanced on a motionless seesaw.Which of the following ismost likely true about the students?

A They have different weights and are equal distances from the pivot of the seesaw.
B
They have the same weights and are equal distances from the pivot of the seesaw.
С
They have different heights and are different distances from the pivot of the seesaw.
D
They have the same heights and are different distances from the pivot of the seesaw.

Answer 1

For two students to balance on a seesaw, they must satisfy equilibrium conditions, requiring them to have different distances from the pivot if they have different weights.

Step-by-step explanation:

When two students are perfectly balanced on a motionless seesaw, they must be in a state of equilibrium. This can be achieved when the torques produced by both students about the pivot are equal. For this to occur, if the students have different weights, the heavier student must sit closer to the pivot point (fulcrum), and the lighter student must sit farther from the pivot. Since they are in balance, equilibrium conditions are met. Therefore, the most likely scenario is that the two students have different weights and are situated at different distances from the seesaw's pivot to balance the torques.

Answer 2

The answer is probably b
